On the Volvo DVD nav drive, the CD laser is only used for software updates, and the DVD laser is used for reading the map DVDs.
So the CD has much less operational hours on it that the DVD laser.
This is often why the CD can be read OK but the DVD is more difficult to read.
If a DVD drive can read a CD but struggles to read a DVD then it is normally one of two things:
1. CD Laser is OK but DVD Laser is old and weak. You can try cleaning (see point 2), but if that doesn't work the only solution is a new laser (or new drive, or new nav unit)
2. Laser lens is dusty / dirty. A gently clean with a cotton bud and isopropyl alcohol or window cleaner (streak free) is called for. You want to remove the dust and grime from the laser lens. Affects CD and DVD reading equally, but if the DVD laser is weak and the CD laser is strong, then the effect can be more noticable when reading DVDs.
